It means they can be exfoliated into nanosheets that less than one nanometer thick As layered materials, transition metal dichalcogenides(TMDs) like molybdenum disulfide(MoS2) have attracted many interests due to their outstanding electronic properties. Recently, we have developed a new simple method for the exfoliation of TMDs by using Na/K alloy through liquid-phase. We have synthesize few-layer MoS2, molybdenum diselenide(MoSe2), tungsten disulfide(WS2), tungsten diselenide(WSe2) four compounds. Characterization of the exfoliated materials was done by X-Ray Diffraction(XRD), Raman Spectroscopy, Transmission Electron Microscopy(TEM). We also tested these exfoliated materials for the lithium-ion batteries.Also, we used this two-solvent interface trapping method to exfoliation molybdenum disulfide(MoS2) and hex-boron nitride(h-BN). For this method we expect to make some large-scale thin film by exfoliated materials. Characterization of the exfoliated materials was done by Raman Spectroscopy, Transition Electron Microscopy(TEM), Scanning Electron Microscopy(SEM). 2015-06-01 English text University of Akron / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=akron1428063152 http://rave.ohiolink.edu/etdc/view?acc_num=akron1428063152 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
